Under unusual conditions where it is not possible to obtain a soil test, the following soil amendments will be applied: For Permanent Seeding: Seeded areas shall be limed at a rate of 2 tons per acre, and fertilized at a rate of 1,000 lbs. per acre of 10-20-10 (10 lbs. per 1,000 square feet) or equivalent. For Temporary Seeding: Seeded areas shall be limed at a rate of 2 tons per acre, and fertilized at a rate of 600 lbs. per acre of 10-20-10 (10 lbs. per 1,000 square feet) or equivalent.

Minimize the discharge of pollutants from spills and leaks and implement chemical spill and leak prevention and response procedures as follows. Most spills can be cleaned up following manufacturer specifications. Absorbentloil dry, sealable containers, plastic bags, and shovels/brooms are suggested minimum spill response items that should be available at this location. In Priority: Protect all people 2i4 Priority: Protect equipment and property Yd Priority: Protect the environment 1. Check for hazards (flammable material, noxious fumes, cause of spill) — if flammable liquid, turn off engines and nearby electrical equipment. If serious hazards are present leave the area and call 911. LARGE SPILLS ARE LIKELY TO PRESENT A HAZARD. 2. Make sure the spill area is safe to enter and that it does not pose an immediate threat to health or safety of any person. 3. Stop the spill source. 4. Call co-workers and supervisor for assistance and to make them aware of the spill and potential dangers. 5. If possible, stop spill from entering drains (use absorbent or other material as necessary). 6. Stop spill from spreading (use absorbent or other material). 7. If spilled material has entered a storm sewer, contact locality's storm water department. 8. Clean up spilled material according to manufacturer specifications, for liquid spills use absorbent materials and do not flush area with water. 9. Properly dispose of cleaning materials and used absorbent material according to manufacturer specifications.

I agree to provide erosion control measures in accordance with the Handbook standards and specifications to protect against the transport of soil and sediment off of the property. I further agree to comply with additional requirements determined necessary by the Program Authority. Such requirements shall be based on established conservation standards and shall represent the minimum practices that Albemarle County deems necessary to provide adequate control of erosion and sedimentation on or resulting from this development. At a minimum, the following to the following measures will be implemented: 1. Silt fence, sediment traps and other protective measures must be provided in areas where sediment from disturbed areas may leave the site, and must be properly installed before land disturbance. These measures must remain installed and maintained until adequate stabilization is achieved as determined by the Program Authority. 2. All erosion measures are subject to inspection periodically and after each runoff -producing rainfall event. Any necessary repairs to maintain the effectiveness of the erosion control devices and cleanup of sedimentation must be made immediately. If erosion control measures are found to be inadequate, or in need of repair, by a county inspector, you will be notified. A fee of $176.80 will be charged for the first reinspection and $280.80 for each subsequent reinspection that is necessary. 3. A temporary stone construction entrance must be provided wherever traffic will be leaving the construction site and where there exists the possibility of transporting mud directly onto a road or other paved area. 4. All denuded areas on the site must be stabilized within seven (7) days of final grading with permanent vegetation or a protective ground cover suitable for the time of year. Temporary soil stabilization must be applied within seven (7) days to denuded areas that may not be at final grade but will remain dormant (undisturbed) for longer than thirty (30) days. 5. A permanent stabilization/vegetative cover must be established on all denuded areas within nine (9) months of the start of clearing or grading. Unless documented in writing to the Program Authority at the start of land disturbance, the nine (9) months will be measured from the permit issuance date. If an extension is necessary and construction extends for more than a year, a permit maintenance fee of $170 will be required. 6. During construction of the project, soil stockpiles and borrow areas must be stabilized, covered, or protected with sediment trapping measures. 7. All storm sewer inlets that are operable during construction must be protected so that sediment -laden water cannot enter the storm water conveyance system without first being filtered or otherwise treated to remove sediment. 8. All temporary erosion and sediment control measures must not be removed until disturbed areas are stabilized. After stabilization is complete, all measures must be removed within 30 days, unless otherwise authorized by the Program Authority. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures must be permanently stabilized to prevent further erosion and sedimentation. Stormwater Management Agreement In lieu of submitting a formal stormwater management plan for development of this single-family residence and/or appurtenant structure, I agree to comply with the requirements of the Albemarle County Water Protection Ordinance, County Code Chapter 17, the Virginia Stormwater Management Law, Virginia Code, 9VAC25-850, and 9VAC25-870. I agree to provide stormwater management measures as determined necessary by the Program Authority. Such requirements shall be based on established state standards and shall represent the minimum practices that Albemarle County deems necessary to provide adequate control of stormwater runoff resulting from this development. At a minimum, the following measures will be implemented: I. The site shall be fully stabilized with permanent vegetation or equivalent stabilization with seven (7) days of final grading. 2. For sites within a larger plan of development, all runoff from the house and driveway and developed areas shall runoff as directed on the overall plan, or sheet flow to adjacent vegetated areas. Runoff shall not adversely impact neighboring properties. 3. For sites without a larger plan of development, runoff shall sheet flow to vegetated areas. Such areas shall be natural areas subject to mowing no more than 4 times per year, and at least 100 feet in flow length to the nearest property line, stream, or receiving water. 4. Roof gutters shall be directed to splash blocks or level spreaders to establish sheet flow to vegetated areas as per item 2-3. No concentrated runoff shall be discharged from the property. 5. For site without a larger plan of development, all impervious areas and storm sewer inlets shall be situated so that water cannot enter the storm water conveyance system without first being filtered or otherwise treated to remove potential pollutants as indicated above. Roof gutters shall not be conveyed directly to storm sewer, ditch lines or property lines. Certification: I further understand that failure to comply with such requirements within three (3) working days, following notice by a county official, could result in a citation for violation and may require the submission and approval of a formal erosion and sediment control plan or stormwater management plan with an appropriate performance bond as provided in Section 17-403 and 17-414 of the Albemarle County Water Protection Ordinance. I hereby agree to be responsible for carrying out each of the duties and responsibilities enumerated above, as well as all other requirements of Albemarle County's erosion and sediment control and stormwater management programs. I also hereby agree to maintain responsibility for this permit regardless of the sale of the property prior to completion of the work covered by this permit. 0-4.. 39 M St NW Apt B Washington DC 20001 202-316-5308 thompson.pht@gmail.com Landowner's Signature Street Address, City, State Zip Code Phone No. Email Address VIRGINIA DEPARTMENT OF ENVIRONMENTAL QUALITY 1111 E.
